5251 Aluminum Alloy is the ideal aluminum to UV laser print and C02 laser engrave on. Both our lasers and UV printers leave a beautiful and detailed white mark on the metal for great contrast. This combination gives the artwork a clean and very modern look, perfect for any garage or office. This is our most popular material choice and you get to choose between a number of different options! These come framed in a simple, but elegant metal frame ready to be hung!
